Abstract
Abstract Sulfamo dihydrochalcones of the formula <IMAGE> are disclosed wherein M+ is a physiologically acceptable cation, X is H or OH, and R is a lower alkyl. These materials are useful as sweeteners for edibles. They may be prepared by sulfonating the corresponding amino dihydrochalcone using, for example, catechol sulfate.
